To all whom it may concern: v Be it knownthat I, SWAN LsoN,ya citizen of the United Statesresiding at Minneapolis, in the countyofrHennepin andState of Minnesota, have invented'certain new and useful Improvements in Shock Loaders; and I do. hereby declare the following to be a full, clear, and .exact descriptionof the .invention, such as will enable others skilled in the art to which it appertains to make and use the same.- y

This invention relates to a hay or shock loader and is of the type in which thehay or other material is gathered from .the ground, elevated and deposited on a vehicle.

l It is an object of `this invention to provide such a loader which can be lreadily operated by a'farmtractor., both .forits locomotive movement.. and for its various movements in performing the loading operation. It is a further object ofy theI invention to provide such a loader having a carrier adapted to be` raised ;and lowered vand a power driven rake which will move ythe .material onto the carrier whenthecarrier 1s in its lowered position.-`

It isv another object-of the inventionto provide Vsuch a. carrierr with power elevating and lowering mechanism and with means whereby such power-.mechanism will .be au- .tomatically-v thrown-*out of operation l when the carrier.l reaches itsllowered position.

It isa further object of the invention to so 4construct the-carrier that the same will be automatically dumpedv by the power mechanism but so that the same `can also be dumped at any time desired by manual Ingangl i .y

A still further objectv of the invention is to have ther mechanism for performing the differentmovements of the device all under control olf the' operator-'by means .disposed atthe rear ofthe tractor Within leasy reach of `the voperator when occupying the usual seat for ldrivingthe tractor. 'v

.These and other objects and advantages of the invention will be apparent from -the following description made in connection with'theaccompanying ydrawings in which 1likereference characters refer to the same lparts throughout the different views, andlin whichv Fig. yl is a-'view in side velevationsof .the devife.; l i

The-tractor-'comprises the enginel," the usual transmission mechanism .and transmission shaft 2,- the supporting wheel-S13 `and seat 4. Inaccordance with the` present invention, thetransmission shaft 2 is carried forwardly la'nd-provided with a clutch 5,drivingbev- ,eled gears 6 and a'ldriving sprocket 7 over -whichfa chain 8 is arranged to travel. `Spaced side `frame members -9 are provided for-supporting the loading f' dev-ice and y these are connected at their rear; ends" to the tractor `frame fin. any :desired manner.l At their forwa-rdriportions, the vframe members 9 have securely bolted thereto, spaced upright mem- -bers l0. These members riseat eachside of .the device `andare connected at .their upper ends byiawtransverse beam 1.1. At the lower portion. ofmembe:rs.. l0 .are disposed memlhers1Q-securely fastened thereto and'provided with outwardly extending ybea-'rings adapted 4to :receive axles for vsupporting the wheelsll.. Secured vto the l.front and rear sides' of the `frame formed by `thelmembers l ','10 farejrbow' runner members 14 ywhich :extend under said frame members into close proximity with the ground at each side of the machine. In case uneven portions of the ground are encountered or some slight obstruction or pile of grass or refuse, the device will be assisted in moving thereover by the support of runners 14. A shaft 15 extends along onel side of the frame and has a slidably mounted sleeve thereon carrying a sprocket wheel 15b adapted to receive thereover the chain 8. This shaft, as shown in Figs. 1 and 3, carries at its front end a pair of oppositely facing beveled gears 16a and 16b which are adapted to mesh alternately with the beveled gear 16c on the lower end of a shaft 16 extending upwardly at one side of the machine, as shown in Fig. 2, this shaft being supported in suitable brackets carried by the members 10 and in a bearing disposed in the member 11. The shaft 15 is also provided with clutch members 17 and 18, which, as shown in Fig. 4, are disposed at either side of a clutch member carried on the sprocket over which runs the chain 8. The shaft 15 also carries a collar 19 secured thereto by a set screw or other convenient means and springs 20 are disposed between this collar and the clutch 17 and between the collar and a bearing projecting from the side of the frame member '9 through which the shaft 15 passes. The shaft 15 is adapted to be moved longitudinally to engage the clutches 17 and 18 and to engage the beveled gears at the front end thereof with a beveled gear carried at the lower end of the shaft 16. At its end, a shifting member 21 is provided which is movably mounted `on the frame members 9. This member is of box-like form and has mounted therein two reversely facing L-shaped members 22. The long ends of these members are pivoted at the outer ends of the member 21 and provided with hook-like portions which engage over a leaf spring 23 held therein and which tends to maintain the members in the position shown in Fig. 5. The short legs of the member which are adjacent each other are apertured to receive pivot pins 22a extending through the member 21 and secured in a plate member 24 disposed at one side of the member 21 and projecting thereabove. The shaft 15 extends to the member 21 and is connected thereto by a headed member 25, a small portion ofwhich projects through the end of member 21 and is connected to the shaft 15. The headed member 25 is disposed in a bore or cylindrical passage in the lower portion of the member 21 and this passage is also apertured at the other end of the member 21 to receive a rod 26 having a head 27a on the end thereof. This rod 26 .extends rearwardly along the side of the tractor and is adapted to bereeiprocated by a lever member 27 equipped with the usual spring pawl handle and toothed quadrant therefor, which .lever is disposed within convenient reach of the operator. A reciprocation of the member 26 brings the member 27 L into contact with one fend-of the member 21 or with the member 25 in the other end thereof and thus moves the said. members together with the shaft 15 in either direction. A rod 28 extends longitudinally ofthe member 21 adjacent the top portion thereof and has a cam portion 29 on one end adapted to cooperate with the pin 30 projecting from the plate 24 for a purpose to be later described.

` The shaft 16 above referred to carries at its upper end adjacent the member 11 a spur gear which meshes with a combined spur and beveled gear 31, which, in turn, meshes with the beveled gear on the end of a horizontal shaft 32. This shaft is equippedwith a similar beveled gear at its outer end which meshes with another beveled gear attached to a vertical screw 33. This screw is similar to the screw 33 secured to the first mentioned beveled gear 31 andboth screws are journaled in bearings in the member 11 and extend down centrally between the members 10 and are provided at their lower ends with collars or shoulders adapted to rotate and be held in bearings 34 secured in the frame at the lower portion of the members 10. The l screws 33 are engaged with elongated nuts 35 which are provided at their lower ends with projecting conical portions adapted to be received in conical portions in members 36, the members 36, above the said conical portions being formed with upwardly diverging chambers surrounding the nuts 35. This construction permits a swiveled'action of the members 36 about the nuts v35. The members 36 are vprovided with inwardly extending journal members 36a which are received in bearingsformed on the main supporting member 37 of the cradle or carrier e. This carrier comprises longitudinally extended spaced pointed Yslats 38, vertically extending and spaced slats 39 at the rear thereof aligned with the slats 38, and spaced hori- Zontally extending slats 40 of greater width which passaround the rear and sides of the carrier. The general shape of the carrier in side elevation is shown in' Fig. 1. From the description given, it is seen that the carrier is pivotally mounted on the members 36, which members, as stated, have a slight swiveling movement on the nuts 35 but will 'be carried vertically by said nuts "when the same are caused to traverse the screws 33 by the rotation of the latter.

' A bell crank lever 41 is pivoted at one side of the member 36 shown at the left of Fig. 2 and the short arm of this lever is adapted to be contacted by said member when the same is in its lowermost position. This lever is normally held with the short arm elevated by a tension spring 41a. The

long arm `of "lever 41 extends Vfupwardlyand receives in .its biurcated-vend-:lthe headed fend.'

Itfmay' be stated that when the member 43' is thus movedlto y bring -its upper end init-o contact with the member 37, the arms 43e' will be withdrawn from engagement with the member '36;

The material Iis ada-pted'to be moved "onto 'the carrierl c by the-'rake b. This member comprises longitudinal side 'members 53 which are supportedonl pins-*54 projecting inwardly of the front memberslO, which pins are provided'with retaining collarson their inner ends.

The operation' of'r the device. is asl follows:

Thel machine will f. .beproj ectl'ed a'longvth'e ground with the carrier yc inl its lowermost position; "The: clutch -5 will `beengaged lwith gears 6v to drive the wheel 156' :and i `osci'l'late the lever 54a.. 'Fhisfwil-l movethe ssid'efmember-s 53 of the rake bac'k andiforivard 4and the kfront end Soi." the rake -will be ra'isedfand ias will be moved onto carrier o. When sufficient -material has 4accumulated thereon the operator will manipulate lever 27 and move the shift member 21 yand shaft 15 to engage the beveled gears 1Gb and l16c and the sprocket 15b and clutch member v18 so that the screws 33 will'fbe turned in the direction to elevate the nuts 35. The nuts will carrythe members `56 upwardlytherewith and the carrier @will be elevatedby the pivots. 56:v engage ing member 37. The carrier will move upwardly-in substantially horizontal position, the plate'43 holding the same in this position by engagement with the sides of members 36; rl`he rake Z) is also elevated aty this time by the engagement 'of member '37 with the sidemembers thereot..v The rake being poised by the ysprings 52 willnot require much vpower to elevate it. `When the carrier has approached the upper limit oit its movement its rear end will engage with` .the spring member 66. Just previous to this'en. gagement the extended portions 43 oi plate 43 will engage with the wedge members 67 the position'of which is indicatedin 2 and in dottedlines in Fig. 3 and thesplate 43 will ybe moved-'inwardlyand outoi'- contact with the member 36.' The carrier .c is therefore free to swingforwa'rdly on its pivots and will be caused to'swing by further upward movement since it is in engagement with the member 66. ylhe hay in the c-arrier will thus be discharged and can be received onto a vehicle disposed .in position t0 receive the same.` l v .Ii'thevoperator wishes to dump the mata rial on the carrier c before the carrier reaches its uppermost position, he can do so at any time by turning the rod-48.v This-rod is provided with a convenient upturncd portion at its rear end by which itmay be given a rotating movement. Such. movement will, in turn, turn the shafty 45 and the plate 43 will be drawn inwardly to disengage the up.- standing end of the member 36. The carriage will then swing downwardly on its pivotsr and the materialltherein will be dis charged. l .v

kAfter the carriage has been raised to discharging position, the..lever 27 will be .moved to neutral position with clutches .17 and 18 and gears 162216b and 16c disengaged. Vhen it is desired t0 lower-'the carrier thev `lever will be manipulated-'to move the shift member 21 to engage the clutch '17, and l.sprockets 15b, as well as gears 16al and 16.I This will rotate the screws 33Min a direction to lower the'carrier. When the carrier reaches its lowermost position, the lower end of the member 36 will Contact the lever 41, which lever will-be swung and movev the. rods Y42 and 28 longitudinally.y This4 movement will moventhe inclined portion of themember-.29 under pin 30 and the member 24 will thus be raised carrying with it the. shortinner arms of the ,members 22. It lwill be noted that vtheMhead-Qfon the rod 26 is located betweenv the inner endsof the members 22 and the shift member 21 is .thus heldfrom movement inl respect to the pressure ot springs` 20, one of which is compressed when the. carrier is being lowered. Vhen the membersf22 are raised ,the head 27 is .released andthe springs 2O then act to move the member 2,1 through the connection 25 to brin-g the clutches 17 and 18 and gearsfl'* and-,16b into disengagement or neutral posi#` tion. The screws 33 arevtherefore .stopped and-the carrier rests on its lowermost position.k I

The take-up or tension device 65 as well as springs 52 acts to counterbalance the ralre member b and it will also be noted that this rake ymember can be raised at any time *desired by the operatorgraspingthe cable 63 and pulling the same .over thevsheave 64. i

. In Fig. 8, is illustratedanother method of supporting the loader bythe wheels 13. In-k stead ot' having the members 12 carry the axle. bearing and stub axles therein, one continuous axle .70 can be usedwhich will be dropped'sutliciently at its central portion to pass under the carrier c. j The r'ame'members 71 Awilly correspondto. the frame meinbers 9y and the members 72 to the members 10. The structure'oi the device otherwise will bethe same as already described.
